1. Enhanced Search
This is one of many custom widgets developed by Robert Scheitlin, GIS Manager for Calhoun County in Alabama. The Enhanced Search widget provides the ability to perform a search on a layer, and then performs an additional geometric or spatial search based on the original search string. An example is shown below; in the "By Value" tab of the widget, a parcel ID or address is searched. Switching to the "By Spatial" tab, apply a search distance for a buffer, choose the search layer, and choose the spatial operation for returning results (entirely contained in, intersected by).
The Identify widget is another useful offering from Scheitlin. Rather than using the pop-up window from the webmap, you can use this widget to access a feature's attributes, identify multiple features using geometric operations, and even access an external link associated with that feature.
3. Google Street View
Panoramic, street-level views are available to your app with the Google Street View widget. The only requirement is obtaining an API Key or Client ID from Google.
4. Print Plus
The Print Plus widget was developed by Larry Stout, based on Esri's Print widget. The main features of this widget are an on-screen print area layout, the ability to pan the map inside the layout, and a scale slider.
